Look at code reviews.Seriously. Just look at them. This is step one. You don't need to be added as an assignee or a reviewer, but start looking at them. When you do:
- Look at what files change - how do they relate back to this particular feature/bug fix?
- Look at what comments other reviewers leave - what kinds of things are they focusing on?
- Try and understand what the code change is doing - read through and start to identify what kinds of functions live in the different files.
Set up your laptop with a development environment.You are part of the development team, after all - aren't you? So if your on-boarding as a tester didn't include setting up your environment the way a developer's is, find the docs and do it yourself. Or ask for it. Either way, I encourage that you get set up to pull code and run local builds. Not only does this give you the opportunity to see the code and spend time in the environment that the developers do, but it also allows you to be able to pull branches, run local builds, and get early eyes on features and code changes.
Use the terminal at every opportunity.Just to get used to writing commands, and understanding what the terminal can do for you. There's so much power available to you. Once you learn some of the shortcuts, I promise you'll wish you had explored the environment sooner. This will also help you set a foundation for the skills needed to write bash scripts. Once you have that foundation, you can start to...
Experiment with writing scripts.There are many opportunities for scripts to help you do tasks related to your job much more quickly and efficiently. Once you understand how to do things like cURL from a terminal window, you can start to script things like API calls for testing and validation. Consider any task you spend time doing more than once a candidate for a script. Once you've written a few of these, you'll be on your way to building a library of tools that help you complete menial and tedious actions with minimal effort - freeing you up to spend more time on the most impactful work.
Pair with developers.Get face time with developers whenever you can. In my experience, they often more than willing to let you sit with them, shadow them, and work through problems together. By doing this, you'll see how they tackle problems and if they're really helpful, they'll talk through their process of building the feature with you. You can hear where they start, what kinds of things need to be added, modified or removed, any many other insights into the code base. You can also watch for and discuss coding conventions. Every organizations have their own conventions and standards and you'll want to be familiar with yours so as you learn you ensure that you're learning habits that align with the company. This sets you up to have your first few attempts at code be well received by your friendly neighborhood developers.
